About this 1.3ct lab-grown marquise diamond

This 1.3ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG737578399 or 737578399. Listed at 22 retailers as of November 4, 2026, with prices from $218 to $1,210, a $992 spread on the same certified stone. Brilliant Earth lists it at $1,210. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
